Pre-installation Planning
975-0012-01-02 Rev A 2–5
Wire Routing
Determine all wire routes both to and from the inverter and which knockouts are
best suited for connecting the AC conduits. Possible routing scenarios include:
• AC input wiring from the main electrical service panel to the inverter/charger
(if used)
• AC input wiring from the generator to the inverter/charger (if used)
• DC input wiring from the RE to the inverter/charger (if used)
• DC input wiring from the batteries to the inverter/charger
• AC output wiring from the inverter/charger to the sub-panel
• Battery Temperature Sensor cable from the batteries to the inverter/charger (if
used)
• Remote control cable to the inverter/charger (if used)
• DC ground from the batteries to an external ground rod
• Load circuit wiring rerouted from the main service panel to the sub-panel
Check for existing electrical or plumbing prior to making cuts in the walls. Cut
holes in the walls at appropriate locations for routing wiring/cables.
Electrical Panels and Circuit Breaker Requirements
The following electrical panels and circuit breakers may be required for this
installation.

AC Distribution Panel (Sub-Panel)

Loads backed up by the inverter will need to be rerouted from the main electrical
panel to a sub-panel. This can be done several different ways, depending upon the
installation. Always refer to electrical codes for safe wiring practices.

DC Disconnect

Install a DC disconnect breaker or fuse in the positive battery line. This breaker
protects the DC wiring in the event of an accidental short. Size the breaker in
accordance with the battery cables. Switch this breaker OFF whenever servicing
the batteries.
Battery Considerations
The DR Inverter can support either 12-volt battery banks or 24-volt battery banks.
The battery voltage MUST match the voltage requirements of the inverter. To
determine the correct voltage for the system, check the last two digits on the
inverter’s model number. For example, the DR1512 is a 12-volt inverter and
requires a 12 Vdc battery system. The DR2424 is a 24-volt inverter and requires a
24 Vdc battery system.
